Thermal recording head and process for manufacturing wiring substrate therefor.

摘要

A thermal recording head comprising an insulating substrate (13) which has thereon a heat generating resistor pattern (17) made of a thin-film resistor, an electrode pattern (1 5) having a common power supply electrode pattern portion (1 5A) and a common grounded electrode pattern portion (15B), for supplying the power to the resistor pattern, and a controlling electrode pattern portion (15C), and switching elements (19) for controlling the supply of power to the resistor pattern. The electrode pattern (15) is made of a thick-film copper paste by a printing process. The operation of the switching elements is controlled by the controlling electrode pattern portion (15C).

Also disclosed is a process for manufacturing a wiring substrate for a thermal recording head.
